— 3х + Зу = - 24<br> how do i convert to slope intercept form
shepuryov [24]

Answer:

y = x - 8

Step-by-step explanation:

Slope intercept form:  y = mx + b, where b is the y-intercept.

Solve the given equation for y and then compare the result with this y = mx + b:

3y = 3x - 24

Dividing all three terms by 3 yields:

y = x - 8 (answer).  The slope is 1 and the y-intercept is -8.

The average annual cost of the first year of owning and caring for a cat is $1,500. A sample of 81 will be used. Based on past s
Hunter-Best [27]

Answer:

The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.025 = 0.975, so Z = 1.96.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

Sample of 81

This means that n = 81

What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?

M = z\frac{\sigma}{\sqrt{n}}

M = 1.96\frac{198}{\sqrt{81}}

M = 43.12

The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.
